Isopods of the genus Astacilla (Valvifera, Arcturidae) from the LIFE + INDEMARES project off Alborán Island (S Spain), with the description of a rare species A. carlosoteroi (Reboreda, Wägele & Garmendia, 1994)

Abstract

Three species of the isopod genus Astacilla were collected off Alborán Island (SW Mediterranean Sea) within the LIFE + INDEMARES project. Twelve specimens of the rare species Astacilla carlosteroi (Reboreda, Wägele & Garmendia, 1994) were found; this species is only known as a single incomplete female from Galicia (NW Spain, Atlantic). Males, reported for the first time, are described, as well as morphological details provided for two additional species, A. dilatata (G.O. Sars, 1883) and A. mediterranea Koehler, 1911.
